T 0 all whom it may concern:

Be it known that I, ANoUsMoKELLAR, a citizen of the United States, residin at Salt Lake City, in the county of Salt L ake and State of Utah, have invented new'and useful Improvements in Visible-Measure Dispensing Apparatus, of which the following is a specification.

This invention relates to liquid dispensing apparatus and pertains particularly to dispensing apparatus for the dispensing of gasolene and motor fuel.

The construction provides a measuring dispensing apparatu having a transparent calibrated receptacle adapted to receive fluid from a pump, and which is adapted to empty the required amount and to return the unused amount into the storage tank.

The construction also provides a visible measuring and dispensing apparatus in which a drain valve communicating with a storage tank and within a transparent receptacle is adapted to remain closed until actuated by the operator or until a dispensing hose is hung on a valve handle.

The invention relates particularly to the details of construction providing the sup-,

ply pipe and overflow pipe for the receptacle, and the unitary one-piece construction which provides an unusually compact and useful dispensing apparatus.

The construction provides other usefulcombination of a storage tank, a pump, and a transparent dispensing receptacle and particular pipe connections and valves between these parts. The apparatus is designed so as to provide a visible measuring and liquid dispensing machine so constructed that both seller and purchaser can at all times see the How of liquid from the pump to the dispensing receptacle and from the latter to the vessel or automobile tank which is to be filled. The dispensing receptacle is graduated to conform to actual measurements and the graduations may be verified by the proper official acting as sealer of, weights.

and measures. The liquid can be withdrawn from the dispensing receptacle only through the dispensing hose or by the automatic drain valve which latter is within the receptacle and in plain view. if the seller were to manipulate the control handle which projects from the automatic drain valve this movement could easily be detected by the porches re and natures of the .ceive fastening rods ventio-n are described and claimed in the following specification and claims and illustrated in the accompanying drawings, in which Figure 1 represents in partial section an elevation of the dispensing apparatus, showing the positions of the drain valve, the supply pipe opening, and the mounting of the overflow pipe with respect thereto;

Fig. 2 is a top plan view of the lower base member of the receptacle;

Fig. 3 is a sectional view taken on the line 33 of Fig. 2, and

Fig. 4 is a view of the base member shown in Fig. 2, looking upward.

Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 3, and showing the construction of the radially extending supply pipes.

eferring in detail to the apparatus, a storage tank is indicated by 1, and immedi ately above the same is the casing 2 for a pump member, not illustrated. The pump and easing are mounted on a suitable supporting structure indicated by the concrete base 3 above the storage tank 1, and-this casing extends upwardly as a supportmemher for the dispensing receptacle-mounted at the upper end. This receptacle constitutes a distributing chamber and is preferably cylindrical in shape and is formed of heavy transparent glass 4-. The lower end of the glass cylinder is supported on a cast iron base 5 which is rigidly secured to the supporting casing 2. The cylinder 4 is sunk into an annular depression 6 in the base 5 and is packed with suitable material to preventthe escape of the liquids from the dispensing receptacle. is to be dispensed it has been found convenient to use a combination of cement and shellac to prevent the seepage of the mate rial from the lower end of the glass cylinder. The upper end of the cylinder 4 is covered by cast iron covering plate 7 which is similar to the base plate 5 and which has a corresponding annular groove or depression 6 to correspond with the depression 6 of the base plate 5. The plates 5 and 7 are provided with extensions 8 adapted to r the base plate 5 to the top plate 7 and are adapted to be tightly fastened to clamp the glass cylinder t between the same. The de tails of design of the base plate 5, which will be elaborated hereinafter, hare im- Where gasolene or oilv 9 which extend from Lilli 14 and is screw shown) and screw threaded into the opening] 10 in the under "side of the base plate 5.

. The dispensing hose 11 is secured to a pipe I 12 which is screw threaded into the opening 12 in the base plate 5. At the extreme end of the dispensing hose 11 is the usual delivery nozzle 11 which when not in use is adapted to hang on the valve handle as will be described. The drain'pipe 13 isscrew threaded into an opening 13 in the lower side of the base plate 5 and extends downwardly to the tank 1. An overflow pipe is shownat threaded into an opening 14* in the upper side of the base plate 5 and immediately over the. supply 10*. The base platefas illustrated is thicker at its central portion and provides for an upwardly extending central chamber, having walls 10", formed as a continuation of the opening 10. The opening 14 extends inwardly and encircles the walls 10"v and is continued aS a conduit 15 extending to the opening 13 The up er end of the supply pipe has laterally projecting suppl pipes 10, extending from the central cham er and from the walls 10 across the space of the encircling conduit 15 and through the upper surface of the base plate 5 at the base of v the overflow pipe 14. The drain valve openillustrated as positioned above the opening13 andvformed in the upper face of the base plate 5. The conduit 15 constitutes an unobstructed passageway continuously functioning to carr 01f any overflow of superfluous gasolene rom the overflow e 14 to the return pipe 13. The present construction is peculiarly advantageous because the single base member 5 contains in tegrally and compactl formed therein the passageway for over ow material 15, the

ing 16 is drain valve opening 16, the return pipe opening 13"v for both the ing 14 and the drain valve 16, in addition to the supply pipe opening 10 and the lat within the peripheral boundar' T hat is no pipes extend latera' ly or pro ect 14: andfthe drain opening overflow pipe openeral'pipes-10, An important feature is provided by the arrangement of having all of the pipes compactly positioned 'elther above or beneath the base member 5 and of the same.

beyondthe outer edge of the base member 5. This compactness of construction is in part due to the fact that'a single pipe 13 serves as a return pipe for both the overflow pipe 16. By having the common communicating passageway 15 formed within the base member 5, it is .thus' possible to: dispense with the otherwise necessary exterior pipe connections-and at pipe opening valves may be added leait one additional pipe below the receptac e.

As illustrated in Fig. 1 the filling receptacle is designed to contain gasolene or other liquid whi pensed. A rod 17 is fastened in said receptacle and held at its upper and lower, ends by the plates 7 and 5 respectively. Along this rod are the number plates 18 which are tengallons of h is to be disprovided with the numbers from 0 to 10 arranged with the 0 number at the top and on a line with the top rim of the overflow pipe 14.- The positions of these indicating numbers 18 may be determined by the oflicial sealer of weights and the machine is being inspected.

An automatic drain valve 19 is provided within the glass to normally close the opening 16. his valve member is pivoted at one side of the opening as indicated at 20 and is adapted to be rocked by means of a controlhandle 21 which extends upwardly and projects from. the top of the dispensing receptacle through an opening 22 in the top plate 7 The controlhandle 21 extends to one side of'the plate -7 and is provided with the hook-shaped end 23 constituting supporting means for the end of thedispensing hose 7 .11 and the nozzle 11*. is provided within the receptacle and is mounted to exercise a "constant pressure against the drain valve 19 to normally hold A spring member 24 the valve 19 in the closed position, that is The weight of". the l closing the opening 16. I hose 11 when hung on'the'hook 23 is suflicient to move the valve measures when cylinder 61 and is adapted handle 21 and rock the valve 19 on the pivot 20 and permit any liquid within the receptacle to drain pipe 13. Inthe operation of thefap aratus, when the liquid is discharged into the glass cylinder 4 through the pipe 1 0 and through pipes 10, it may not be withdrawn from the (cylinder except through the dispensing hose 11 unless the operator of the machine opens the automatic drain valve 19, whichaction would be visible to the purchaser tion to the advantage that the apparatus providesin making it difficult for a salesman to provide a purchaser ure, the apparatus provides means for draining the dispensing receptacle each time that the apparatus is used. quantity is. drawn ofl',=the on the hook 23'; the valve handle 21 is moved to the-left in the slotted opening 22," the automatic drain valve 19 is raised; and the liquid which is left in the dispensing cylinder 4 is allowed to return through the pipe 13. to the storage tank 1. i

The dispensing pipe 12-is provided "with.

pass into thev 'In fiddl with short meas-' When the required.-

hose" 11 is hung 1 and below over the ordinary liquid to become quiet and level.

sence of foaming and gushing is due to thetion with said venient. One of the fastening rods -9 is substituted by a pipe member 9* to shield a wire 24 for an electric lamp 25 mounted on the upper cover plate member 7. In this way the pipe 9 serves not only as a protection for the wire but as a fastening rod, suitable clamping screws being provided on the pipe 9 above the upper plate member 7 the base plate member 5.

In addition to the above features, the present apparatus provides an improvement dispensing pump station which is acknowledged to be faulty in that shortmeasure is quite ordinarily provided because of worn pump parts and the resultant leakage.

Another feature of advantage resides in the construction which locates a plurality of supply pipe openings about the base of e overflow pipe. By this arrangement the filling operation is performed quietly with a steady flow of liquid and there is no gushing or foamingin the liquid. The gasolene is supplied evenly through the plurality of openings 10 and does not become turbulent and foamy when supplied. The gasolene can be drawn off immediately after filling the rece tacle to the proper point without the dc ay common in some apparatus where the operator and customer must Wait for the air to pass foaming to subside, and the surface of the This abarrangement of supply pipe openings which 'prowide an even and balanced supply on all sides of the receptacle as contrasted to the use of single supply pipes or an overhead supply pipe. Single pipes in the base of the receptacle and overhead supply pipes entrap considerable quantities of air and thus cause marked periods of delay for the salesman and customer while waiting for the air to pass off.

Changes in material and size and shape of the parts, as well as changes in the relative positionsof the receptacle, pump, and storage tank, may be made without departing from the scope of the invention.
